Answer:
c³ + cd³ + 3c²d + 3cd²
Step-by-step explanation:
(c+d)^3 is worded as <em>c plus d quantity cubed</em> which doesn't mean you cube everything inside. It means you multiply the quantity by itself 3 times.
(c+d)(c+d)(c+d)
<em>You can only multiply 2 at a time so do the first two then the result and the third one.</em>
<em>Distribute everything in one quantity to the other so </em><em>c*c = c^2 and c*d = cd</em>
= (c^2 + 2cd + d^2)(c+d)
= c^3 + c^2d + 2c^2d + 2cd^2 + cd^2 + cd^3
<em>Combine like terms</em>
= c³ + 3c²d + 3cd² + cd³
Answer:
250 bottles and 150 bags of trail mix.
Step-by-step explanation:
You multiply 250 times 3.5 and get 875. Then you multiply 150 times 4 and get 600. Then add 875 plus 600 and get 1475.
Answer: y>−5
Step-by-step explanation: Let's solve your inequality step-by-step.
−7<2y+3
Step 1: Flip the equation.
2y+3>−7
Step 2: Subtract 3 from both sides.
2y+3−3>−7−3
2y>−10
Step 3: Divide both sides by 2.
2y

Answer:
$32.50
Step-by-step explanation:
The equation for simple interest is
Simple Interest=P×r×n
where:
P=Principal amount
r=Annual interest rate
n=Term of loan, in years
so
P=200
r=0.0325
n=5
so 200*0.0325*5=32.5
